What is a statistical question?When a question can be answered statistically, it can be done so by gathering and analysing data, for example. This particular question aims to comprehend a population or a phenomenon by using numerical data. In contrast to non-statistical questions, which are more concerned with acquiring information or opinions, statistical questions are more concerned with getting and analysing data. Statistical procedures including sampling, data analysis, and inference are frequently used to answer statistical issues.

13 A young girl standing on a cliff is throwing stones up into the air so that they land in the ocean below. The height h, in meters, of each stone above the ocean is related to the
time 1, in seconds, after it has been thrown by the function
h = -21? + 21 + 40. What is the maximum height reached by
each stone?
Answers
The maximum height reached by each stone is 40.5 meters.
The height of each stone above the ocean is given by the function:
h = -2t² + 2t + 40
This is a quadratic function in standard form, with a = -2, b = 2, and c = 40.
The maximum height reached by the stone occurs at the vertex of the parabolic curve described by this function.
The t-coordinate of the vertex is given as:
t = -b / 2a
Substitute the values of a and b,
t = -2 / (2×(-2)) = 0.5
So the maximum height is reached 0.5 seconds after the stone is thrown.
To find the maximum height, substitute the value of t into the function:
h = -2(0.5)² + 2(0.5) + 40 = 40.5 meters
Therefore, the maximum height reached by each stone is 40.5 meters.

One interior angle and one exterior angle are marked on the 7-sided shape

Calculate the size of the exterior angle x.

Answers
The size of the exterior angle in the given 7-sided shape, as shown in the image attached below is: x = 46°.
How to Calculate the Size of the Exterior Angle of a Polygon?To calculate the size of the exterior angle in a polygon when the interior angle is known, we can use the following relationship:
Interior angle + Exterior angle = 180°
Given that the interior angle measures 134°, as shown in the image below, we can substitute it into the equation:
134° + Exterior angle = 180°
To isolate the exterior angle, we subtract 134° from both sides of the equation:
Exterior angle = 180° - 134°
Simplifying further:
Exterior angle = 46°

Using the following conversions between the metric and U.S. systems, convert the measurement.
Round your answer to 6 decimal places as needed
1 meter≈ 3.28 feet
1 Lite≈ 0.26 gallons
1 kilogram≈ 2.20 pounds
15.048 dL≈ qt
Answers
15.048 deciliters is equivalent to 1 quart.
What is conversion?Conversion is the process of changing a quantity from one unit of measure to another unit of measure using a conversion factor or a formula.
We have:
To convert meters to feet, multiply by 3.28.
To convert liters to gallons, multiply by 0.26.
To convert kilograms to pounds, multiply by 2.20.
To convert deciliters to quarts, divide by 15.048.
Let's use these conversions to convert the given measurement:
15.048 dL = qt
Dividing both sides by 15.048, we get:
1 dL = qt/15.048
Multiplying both sides by 0.946353, which is the number of quarts in a liter, we get:
0.946353 dL = qt/15.048 * 0.946353
Simplifying the right-hand side, we get:
0.946353 dL = qt/15.961
Multiplying both sides by 3.78541, which is the number of liters in a gallon, we get:
3.78541 * 0.946353 dL = 3.78541 * qt/15.961
Simplifying the left-hand side, we get:
3.58702 L = qt/4.22676
Multiplying both sides by 4.22676, we get:
15.1485 L = qt

\(\qquad \sf \dashrightarrow \: 816 = 600 + 5400r\)

A university is interested in determining the average statistics anxiety score for all undergraduate students in the U.S. For a random sample of 33 undergraduate students, it is found that the average average statistics anxiety score is 39.4 with a standard deviation of 0.9. Assume that the statistics anxiety scores for all undergraduate students in the U.S is normally distributed. A 98% confidence interval for the true mean statistics anxiety score μ is closest to.
Answers
The 98% confidence interval for the true mean statistics anxiety score μ is approximately (39.023, 39.777).
To calculate the 98% confidence interval for the true mean statistics anxiety score μ, we can use the formula:
\(\[\text{CI} = \bar{X} \pm Z \cdot \left(\frac{\sigma}{\sqrt{n}}\right)\]\)
where \(\bar{X}\) is the sample mean (39.4), Z is the Z-score corresponding to the desired confidence level (in this case, 98% corresponds to a Z-score of 2.33), σ is the population standard deviation (0.9), and n is the sample size (33).
Plugging in the values, we get:
CI = 39.4 ± 2.33 * (0.9/√33).
Calculating this expression, we find:
CI = 39.4 ± 2.33 * (0.162),
CI ≈ 39.4 ± 0.377.
Therefore, the 98% confidence interval for the true mean statistics anxiety score μ is approximately (39.023, 39.777).
This means that we are 98% confident that the true average statistics anxiety score for all undergraduate students in the U.S. falls within this interval.

lebron walked 4 1/2 miles to library in 2 1/4 hours. he walked the return trip at the same average rate , but a different route, taking my 2 1/2 hours. How many miles did lebron walk on the return trip?
Answers
Answer:
5 miles
Explanation:
First, we need to transform the mixed number into decimal numbers using as follows:
\(\begin{gathered} 4\frac{1}{2}=4+\frac{1}{2}=4+0.5=4.5\text{ miles} \\ 2\frac{1}{4}=2+\frac{1}{4}=2+0.25=2.25\text{ hours} \\ 2\frac{1}{2}=2+\frac{1}{2}=2+0.5=2.5\text{ hours} \end{gathered}\)Now, the average rate was the same, so the ratio of the miles to the hours is always the same. Therefore, we can write the following equation:
\(\frac{\text{Miles}}{\text{Hours}}=\frac{4.5\text{ Miles}}{2.25\text{ Hours}}=\frac{x}{2.5\text{ Hours}}\)Where x is the number of miles that Lebron walked on the return trip. So, solving for x, we get:
\(\begin{gathered} \frac{4.5}{2.25}=\frac{x}{2.5} \\ \frac{4.5}{2.25}\times2.5=\frac{x}{2.5}\times2.5 \\ 5=x \end{gathered}\)Therefore, Lebron walked 5 miles on the return trip.

The shaded area represents the solution of the inequalities. Hence, points A, C, D and K are the solution of the system.
How to graph system of inequalities?Get y first when graphing a linear inequality with two variables, such as x and y alone on one side. Then, take into account the associated equation that was created by switching the inequality sign for an equality sign. This equation has a line as its graph.
The last step is to choose a point that is not on either line (usually (0, 0) is the simplest) and determine whether or not these coordinates satisfy the inequality. If so, shade the portion of the half-plane that contains that point. If not, shade the opposite half-plane.
Create a comparable graph for each of the system's inequalities. The place where all of the system's solutions overlap is known as the system's solution.
Given that, the inequality is:
